That is quite a denial. After all, investment in clean energy is one of the driving forces of the current US economy. To quote Grist’s figures, “In 2010, global investment in wind, solar, and biomass energy hit $187 billion, exceeding the $157 billion spent on fossil fuel energy. U.S. solar installations more than doubled in 2011. U.S. wind power capacity represents more than 20 percent of the world’s installed wind power. Over 400 manufacturing facilities across the U.S. make components for wind turbines. In July 2011, the Brookings Institute found that the green energy sector has had “explosive job gains” since 2003.”

Not just that, but alternative energy is making a massive impact on the American military. So when Limbaugh says such an industry doesn’t exist, it is just another thing that he is wrong about. Unlike his current controversy, we not expecting a retraction any time soon.

What Rush Limbaugh means is that the wind and solar industries haven't gone cheap enough to replace the systems that are already established across the U.S.
I would love to see the U.S. less oil independent but until it won't cost billions is the day I start pushing a cleaner, safer, and cheaper alternative to oil the day it becomes true. The only thing that would be feasible in today's market is hydrogen.
